I don't know if you're still trying to figure this out. What was the encoder scale set to and how many pulses per rev does the encoder put out. If you're using a quadrature encoder with 250 pulses/rev, the scale should be 16.666667 = (250 pulses/rev) * (4 quadrature counts per pulse) / (60 RPM/RPS).
